I pride myself on the fact that I speak the languages of most of the places I've been to - and even in the case that I don't speak the language, I make sure to pick up a few words before I leave! Most of the places I've been to I've been more than once. I frequently go back to visit friends and have a good catch up. As a result I know the cities rather well. One of my favourite things to do is to walk up to lost looking tourists in Seoul and ask them if they need help. My favourite response is when they tell me they don't speak English...then the fun begins!
